SP-100 nuclear power system. SP-100 (Space reactor Prototype [1]) was a U.S. research program for nuclear fission reactors usable as small fission power systems for spacecraft. [2] It was started in 1983 by NASA, the US Department of Energy and other agencies. [3] A reactor was developed with heat pipes transporting the heat to thermoelectric ...
In the 1992-93 time period, this work was stopped due to the termination of the related SP-100 nuclear power system work and NASA's new emphasis on "better, faster, cheaper" systems and missions. In 2020, a free-piston Stirling power converter reached 15 years of maintenance-free and degradation-free cumulative operation in the Stirling ...
In 1983, NASA and other US government agencies began development of a next-generation space reactor, the SP-100, contracting with General Electric and others. In 1994, the SP-100 program was cancelled, largely for political reasons, with the idea of transitioning to the Russian TOPAZ-II reactor system. Although some TOPAZ-II prototypes were ...
Zvezda produces a large number of kits in various categories, ranging from historical collections with themes including World War I and II; The Middle Ages and the Ancient world of Greeks and Romans; to modern military models as well as a few Science fiction diorama pieces.
Gilbert cloud chamber, assembled An alternative view of kit contents. The lab contained a cloud chamber allowing the viewer to watch alpha particles traveling at 12,000 miles per second (19,000,000 m/s), a spinthariscope showing the results of radioactive disintegration on a fluorescent screen, and an electroscope measuring the radioactivity of different substances in the set.
The ARC-100 is a 100 MWe sodium cooled, fast-flux, pool-type reactor with metallic fuel based on the 30-year successful operation of the Experimental Breeder Reactor II in Idaho. ARC Nuclear is developing this reactor in Canada, in partnership with GE Hitachi Nuclear Energy, with the intent of complementing existing CANDU facilities. [4]
SAFE-30 small experimental reactor. Safe affordable fission engine (SAFE) were NASA's small experimental nuclear fission reactors for electricity production in space. [1] Most known was the SAFE-400 reactor concept intended to produce 400 kW thermal and 100 kW electrical using a Brayton cycle closed-cycle gas turbine. [2]
The tests included thermal, materials, and component validation, and culminated in a successful fission trial at full-power. Various faults in the supporting equipment were simulated to ensure the reactor could respond safely. [2] The KRUSTY reactor was run at full power on March 20, 2018 during a 28-hour test using a 28 kg uranium-235 reactor ...
